Overview  
</h2>
<P>
This sample demonstrates how to use the Intel  
<sup>
&reg;  
</sup>
Integrated Performance Primitives (Intel  
<sup>
&reg;  
</sup>
IPP) to create an H.263 decoder. Currently H.263 decoder supports baseline profile plus Annexes D, F, G, I, J, M, O, P,&nbsp;S, T of the ITU-T Recommendation H.263 (01/05).
